Well, it depends if your data is valuable enough.
Most modern ransomware are a part of RaaS (Randomware as a Service), and authors are relatively "trustable", so you can pay them and get your files back. Nowadays it's basically impossible to crack a ransomware, because most flaws have been fixed, and those who cannot well encrypt your files are nearly all upgraded (unless you infected from a sample during 2016-2017.
I helped a few companies solving their ransomware issue back in 2015. One case I had dealt is having its private key XORed under C:\Temp\ntuser.dat (weird name, haha). Another case I had managed to do is solved by using the dump file, because the victim is a driver developer, and the ransomware incorrectly encrypted her configuration file for the device driver, so the kernel crashed in WinDBG.
However, modern ransomware can make correct assumption of which file should be encrypted, and carefully design their key function, so low hanging fruits have gone. Nowadays, all companies claiming they can solve the file, are mostly fraud.
Good luck
